       THIS  FUNCTION  IS  DEPRECATED.   New  applications  should  use PQregisterTypes.  This function is now a
       wrapper to PQregisterTypes.

       The PQregisterUserDefinedTypes() function allows an application to  register  one  or  more  user-defined
       types at runtime.  User-defined types are custom types in a backend that implement their own C procedures
       for in/out/send/recv.

       This function must execute a query against the backend to retrieve type information for each user-defined
       type,  thus  this should not be called from within a transaction.  It is recommended to register multiple
       types at the same time to avoid round trip overhead.

       The types argument is an array containing count user-defined types to register.  If  any  type  does  not
       exist, the register is aborted.  Either typput and/or typget must be specified for each type in the types
       array.

       NOTE:  The  typname  member  of  the  PGregisterType  structure can optionally contain the type's schema:
       schema.typname.

       WARNING: PQparamCreate is only aware of types that have already been registered.  If you need  to  put  a
       type into a param, make sure it is first registered.

       User-definedTypesRegistration
       This example registers two user-defined types.

              PGregisterTypetypes[]={{"graphics.rgb",rgb_put,rgb_get},{"graphics.digon",digon_put,digon_get}};if(!PQregisterUserDefinedTypes(conn,types,2))fprintf(stderr,"PQregisterUserDefinedTypes:%s\n",PQgeterror());

       None.

       On  success,  a non-zero value is returned.  On error, zero is returned and PQgeterror(3) will contain an
       error message.
